The perturbed motion in the neighborhood of regular precession of a dynamically symmetric satellite on a circular orbit is studied. The " Norma " specialized program package [1,2], intended for normal-ization of autonomous Hamiltonian systems by means of computer algebra, is used to obtain normal forms of the Hamiltonian. A full catalogue of non-resonant(More)
Algorithms of numeric (in exact arithmetic) deduction of analytical expressions, proposed and described by Shevchenko and Vasiliev (1993), are developed and implemented in a computer algebra code. This code is built as a superstructure for the computer algebra package by Shevchenko and Sokolsky (1993a) for normalization of Hamil-tonian systems of ordinary(More)
